More Information
Summary:A medical device for insertion or implantation in a body includes a polymer substrate and a layer of poly(vinyl pyrrolidone-alt-maleic anhydride) formed on a surface of the polymer substrate. Polymer chains of the poly(vinyl pyrrolidone-alt-maleic anhydride) are entangled with the polymer substrate. L'invention concerne un dispositif médical à insérer ou à implanter dans l'organisme comprenant un substrat polymère et une couche de poly(vinyl pyrrolidone-alt-anhydride maléique) formée sur une surface du substrat polymère. Les chaînes polymères du poly(vinyl pyrrolidone-alt-anhydride maléique) sont enchevêtrées dans le substrat polymère.
